Completion of the isomorphous Ln(trensal) series

The CeIII, PrIII, NdIII, GdIII and YbIII complexes of the heptadentate ligand 2,2´,2´´-tris(salicylideneimino) triethylamine, H3trensal (in its trianionic form), have been synthesized and characterized structurally by X-ray crystallography. These five [Ln(trensal)] structures complete a rare isomorphous and isostructural series of lanthanoid complexes in the trigonal P–3c1 space group with a ≈ 13.1 and c ≈ 16.5 Å
